't'ul Improvements in Oil-Burners, of which the following is a specification, reference being had to the accompanying drawings.

The object of my invention is to produce improvements in retort vaporizing hydrocarbon burners by which the eliiciency of the burner is increased; the combustion of the fuel is more completely effected; and the efficiency of the burner under a low pressure of oil is improved. AAt the same time, by my invention, the adaptability of the burner for use in exposed localities is enlarged.

,In the accompanying drawings: Figure 1 Fig. 2 is a view taken at right angles thereto. Fig. 3 is a section on the line a-b of Fig. 1. Fig. 4 is a section on the line c-d of Fig. 2. Fig. 5 is a top plan view of the base of the burner.

Referring to the gures on the drawings, 1 indicates a flangewhich, with a diaphragm preferably constitutes the dish-shaped base of my burner within which, as will hereinafter appear, takes place the initial combustion or priming of the machine.

3 indicates a generator which preferably consists of a hollow casting provided with hollow legs 4 communicating with the interior thereof.- This interior is supported upon the base by suitable means, preferably by a tube 5, screwing into an opening in the base and into one of the hollowlegs 4. The opening 6 constitutes the oil supply opening and it is designed to communicate witha source of oil supply, not illustrated. The remaining leg 4 carries atube 7 which extends upwardly y into the generator above its bottom wall, as is clearly illustrated in Fig. 4 of the drawings.

Near its lower end the tube 7 is provided with a vent S and is bent so as tobring the vent directly under the middle pa-rt of the axis ofthe generator. This middle part, as illustrated, consists of a removable plug 9 tightly tting within and completely closing a central aperture 10 that extends entirely through the generator. A cylindrical wall 11 defines the aperture 10 and the interior The lower end of the 'plug 9 and the exterior of the bottom wall of theretort are finished'liush with each other and are, collectively, somewhat inverselyconoidal in shape, the axis 12 of the plug forming the apex. The office of the aperture 10 being exclusively for affording,

ever, they atford convenient means of gaining access to the `burner for cleaning purposes, I prefer to employ a central aperture in connection with the plug.

13 indicates a combustion chamber, pref-- erably cylindrical in shape and preferably vIixedly supported by-a paii1 of airsupply branches or ducts 14, a little above the vent 8. The number of air branches is immaterial and they are employed to support the comp bustion chamber because, their object being to supply thereto fresh air drawn preferably from beneath the plane ofinitial combustion, they may be conveniently cast with the case andthe combustion chamber in one piece.

By the arrangement illustrated, an air space 15 communicating with the lower part of the combustion chamber is provided around the lower end of the pipe 7 and adjacent to the vent 8.

16 indicates an annular disk or ange pref- Y erably adjustably carried between the combustion chamber and the generator and in Vclose proximity to both. Its office is to pro-` port an initial combustion, when the flow of oil is stopped. The oil in the base is then ignited and the products of the combustion, passing up against the bottom of the generator, vaporize the oil contained therein, whereupon the vapor, passing out of the vent 8,' is ignited and, supported by the air withinthe .combustion chamber 13, issues from the upper end thereof in a clear ame. This flame, striking against the deiecting conoidal bot- ICQ tom of the generator, is distributed over the surface and serves to keep the generator in continuous and perfect operation. process of vaporization has been commenced within the generator, the oil necessary to the initial combustion is quickly consumed, being no longer required. y

One advantage of providing the generator with a detlecting bottom in a burner of this class and locating the combustion chamber below it, is that all the heat from the combustion chamber exerts its effect upon the generator so that it is possible to keep the burnergoing with the lowest oil supply pressure. TNithout this arrangement, when the pressure is reduced below a certain point, the

Y generator becomes too cool, the vapor ceases to pass outjfrom the jet, and the flame becomes extinguished.

Another advantage of this form of burner, relating especially to the locating of a combustion chamber in close proximity to the jet beneath the generator and in communication with air supply branches communicating with the pure air below the plane of initial combustion, is that the air is supplied directly to the place where it is most needed to promote perfect combustion while the burner is in full operation. Moreover, the combustion chamber tends to protect the vent 8 from the fumes of the initial combustion, which would otherwise tend to exclude or vitiate the fresh air supplied through the branches or ducts This smothering of vapor which first is- After the sues from the Vent 8 is not only wasteful and therefore objectionable, but tends to produce an accumulation of carbon upon the parts, which tends to interfere with the perfect operation of the machine.

What I claim is- 1. In a hydro-carbon burner, the combination with a burner and superimposed generator communicating therewith, of an aperture vin the generator extending entirely through the generator, a. plug tting within the aperture, the lower end of the plug and the exterior of the bottom 0f the generator being finished flush with each otherand forming collectively an inversely eonoidal bottom, substantially as set forth.

2. In a hydrocarbon burner, the combination with a base and generator connected therewith, of a tube communicating with the generator and extending underneath the same, a vent within the tube, a combustion chamber located between the generator and the vent, air supply branches communicating with the combustion chamber, the inner walls of said air supply branches defining au air space in the combustion chamber around the end of the tube containing the vent,sub

stantially as and for the purpose specified.

In testimony of all which I` have hereunto subscribed my name.

WILLIAM R. JENKINS.
